Be clever about energy use. You could go raw, though this might mean you have to use electric food processors and/ or fridges, or simply be careful about wastage (don’t boil too much water, etc…). And, if you haven’t already, switch to a renewable energy company - it’ll take less time than it does to preheat the oven.

Build a talking point/ message into the bake. We’re thinking baked alaska complete with a small save the Arctic protest, or a pie shaped like a community hydro project, maybe geothermal mille feuille… Want some inspiration, check out this oil spill cake.

Alternatively, you could just roll your eyes and refuse to participate because cake is unhealthy and it'll only make us all a burden on the very carbon-hungry NHS. But you can’t really send in pictures of that.

If you’re in, get baking and send us your photos and recipes. We’ll feature our faves on the 10:10 site to share with everyone. There’s no prize for this, just the warm happiness of bake well made and shared.
